Abstract:
A 73-year-old woman who suffered from progressive hoarseness for 6 years and dysphagia without pain for 1 year presented with a soft tissue deposition on the posterior region of the vocal cords and narrowing in the subglottic area. Biopsy of this soft tissue and histological examination revealed laryngeal amyloidosis. A tracheostomy and partial removal of the amyloid were performed with general anesthesia. The airway was secured with a smaller diameter endotracheal tube, which was inserted atraumatically with Magill's forceps. The larynx is a rare site for amyloidosis. Laryngeal amyloidosis is fragile and hemorrhagic. Therefore, massive bleeding may occur during intubation. Anesthetists should take care in intubating the tracheas of these patients and be aware of other systemic diseases in laryngeal amyloidosis.
